I admit that it looks strange to have the hills shown but no forest or streams or orchards or swamps - it makes it seem like the battle took place in a desert. But I haven't the foggiest idea how to incorporate full terrain elements with any accuracy whatsoever and end up with a readable map. (The map posted above is deceptive: there was much more forest than shown. Also many orchards, and in lots of cases it was small patches of one then the other.) I suspect that getting rid of the hills is the way to go - and then to roughen up the surface a bit more with parchment-like texture. I'm open-minded and willing to discuss all this, but if you want full terrain details (which I don't think any CC map has) I'll need a volunteer to take over this project who has better skills than I. I have some nice forest graphics and tried to incorporate them; I can't get it to look good. At best I could have some lonely patches here and there, which would be totally inaccurate and not even look very good.

actually it's pretty easy to create forests like the ones in redbaron's image.just take an appropriate brush chose 2 foliage colours for background and foreground (a brown dark green and a yellow light green) then adjust the jitter/scattering/hue/size of the brush and paint your forests. then just add a drop shadow and depending on what you want add just a little bit of bevel. just a hint.

and the hills in redbaron's image are also easy to create. just take a brush and draw the general shape of the hill. then ctrl+click to select that area create a path from that selection. next stroke the path with a brush made of horizontal lines. then you can fiddle with it to get what you want. adjust the hue/saturation, or use a nice grunge brush to delete parts and bits, or add some speckle and noise. just experiment.

Please show me a CC map that has that much background detail. The closest is Austerlitz, which has just 32 terts and shows no forest - just hills and streams. I have 79 terts. The issue isn't how to make hills and trees in Photoshop (though the hills idea sounds awesome), it's how to get that much stuff under what I've already got and still have a readable map. I will NOT sacrifice 80% of readability to get a 20% gain in prettiness. Please show me an actual map I can emulate, if one exists, and then maybe I can go somewhere with this complaint. Imagine trying to add all the CC stuff on top of the map posted by RedBaron!

You don't just gain 20% of prettiness by trying to emulate RBO's map appearance. You gain 100% more than what you have already, not that what you have isn't already good, but i beleive you can do better. Up to you, but i'd give it a go to lift your map, the way you have lifted Rome. I'd certainly like to see some relief on this map, it looks rather flat right now.

Here are some examples where relief effects have been used relatively well apart from Austerlitz

It would appear that development of this map has stalled. If the mapmaker wants to continue with the map, then one of the Foundry Moderators will be able to help put the thread back into the Foundry system, after an update has been made.
